Anodizing - Wikipedia
Ferrous metals are commonly anodized electrolytically in nitric acid or by treatment with red fuming nitric acid to form hard black ferric oxide. This oxide remains conformal even when plated on wire and the wire is bent. Anodizing changes the microscopic texture of …History · Anodized aluminium · Other widely used specifications · Other metals · Dyeing
"Surface Treatment & Finishing of Aluminium and Its Alloys" by Wernick, Pinner & Sheasby from Abe Books or ... Anodized coatings may be removed with caustic soda, i.e., in an alkaline etch tank. But, as should be apparent, this solution will also attack the aluminum substrate -- so timing to remove the article as soon as the anodized coating is ...
What is Anodizing? While an Anodized Aluminum part can stand up on its own, the process can also be used as a pre-treatment for other coatings processes. Anodized Aluminum surfaces offer color stability under ultraviolet rays and do not chip where a painted surface would.
Organic coating treatment includes powder coating, fluorocarbon coating, and grain processing.The purpose of this articles is to introduce some normal methods of aluminum surface treatment: anodizing, electrophoresis and powder coating, and their strengths and weaknesses.
Surface Treatment Of Aluminum And Aluminum Alloys Abstract: ... Anodized metal Metal with an anodic coating, produced by an electrolytic oxidation process in which the metal is converted to a mainly oxide coating having protective, decorative or functional properties.
Electrochemical surface treatment, also referred to as anodising, is a process of increasing the natural oxide layer formed on the aluminium surface when it comes in contact with oxygen. The oxide layer is increased by means of electrical current, which makes the aluminium surface more durable.
TIODIZE Type I is an electrically semi-conductive finish that is used as a pre-treatment for cold extrusion, hot forging and drawing operations, as well as a coating for absorptance and emittance. TIODIZE Type II provides an anti-galling surface and is an excellent surface preparation for dry film lubricants, paints and emissivity coatings.

Aluminum Anodizing Process and Design Guide - MatWeb
Aluminum anodizing is an electrochemical process in which an oxide (anodic) layer is chemically built on the surface of the metal. This oxide layer acts as an insulator and can be dyed in a wide variety of colors.
Chromic acid anodizing or type I anodize results in the thinnest anodic coat of the principal three types; typically on the order of .00002”-.0001” (20 to 100 microinches) per surface. While thin, when properly sealed chromic anodize affords the aluminum equal corrosion protection to the thicker sulfuric and hardcoat type anodize.
A metal surface treated to have two anodized layers or regions may be used in electronic devices. The surface treatment may include performing a first anodization process to create a first anodized layer, removing the first anodized layer at select locations, and performing a second anodization process to create a second anodized layer at the select locations.
